This version contains the following snIPL changes compared to snIPL
V.2.1.9:

snIPL can now access the z/VM systems management API through a SMAPI
request server.
Access through a VMSERVE service machine continues to be
supported.

The new --getstatus option returns the status of the specified LPARs
or z/VM guest virtual machines.

snIPL - simple network IPL is a command line tool which
serves as remote linux image control using basic Support Element (SE)
functions or basic z/VM system management functions on one or more
images. In particular, you can use snIPL to activate and deactivate
virtual System z hardware with Linux instances.

With snIPL in LPAR mode you can load (IPL) an
LPAR from a disk device, send commands to the operating system
and retrieve operating system messages; or reset, activate, or
deactivate an LPAR for I/O fencing purposes. snIPL uses
the management application programming interfaces (APIs)
provided by the HMC or SE. To communicate with the HMC/SE,
snIPL establishes an SNMP network connection to send and
retrieve data. The HMC or SE has to be configured to allow
the the Linux instance where snIPL run to access the API. If
your network is firewall-controlled, udp-port 161 and
tcp-port 3161 have to be opened between snIPL-invoking Linux
system and HMC/SE. In this mode snIPL can be used to boot
Linux on System z in LPAR mode, to send and retrieve
operating system messages, or to reset, activate or deactivate
an LPAR for I/O fencing purposes.

With snIPL in z/VM mode you can log on, reset,
or log off a z/VM guest virtual machine.
snIPL can access the systems management API through a
z/VM SMAPI request server available as of z/VM 5.3.
For z/VM 4.4 to z/VM 5.4 snIPL can access the systems
management API through a VSMSERVE service machine on your z/VM
system.
For setup information see README.snipl.

snIPL for STONITH provides a STONITH plug-in.
The STONITH implementation is part of the Heartbeat framework of
the High Availability Project. STONITH is usually used as part
of this framework but can also be used independently. For
a general description of the STONITH technique see:
http://linux-ha.org/wiki/STONITH The latest STONITH
release can be downloaded from
http://linux-ha.org/wiki/Downloads. With snIPL for
STONITH you can activate, deactivate, and reset Linux instances
in LPAR mode or running as z/VM guests. snIPL for Stonith
supports the remote image operations activate, deactivate, and
reset, exploiting basic System z Hardware Management Console
(HMC) and Support Element (SE) functions for Linux running in an
LPAR and of basic z/VM System Management Functions for Linux
running under control of z/VM.

To compile and use the
STONITH plugin lic_vps, the Linux-HA packages Heartbeat, Cluster
Glue, and Resource Agents have to be downloaded from
http://linux-ha.org/wiki/Downloads and installed.

Note: As of version 2.1.3, snIPL supports STONITH
version 2 only. Older snIPL versions support STONITH version 1 only.

Please refer to the README and manpage in the tarball for further
information and restrictions.
